GlusterFS is a clustered file-system capable of scaling to several petabytes. It aggregates various storage bricks over Infiniband RDMA or TCP/IP interconnect into one large parallel network file system. GlusterFS is one of the most sophisticated file systems in terms of features and extensibility. It borrows a powerful concept called Translators from GNU Hurd kernel. Much of the code in GlusterFS is in user space and easily manageable.
